Hello Shailendras33,
Congratulations on your new MacBook Pro! Thank you for providing all the information about what is going on with the charging issue.
Firstly, I found some information on page 11 of the MacBook Pro User Guide about what each color of the LED means on the Power Adapter:
When you first connect your power adapter to your MacBook Pro, an indicator light on the
MagSafe connector starts to glow. An amber light indicates the battery is charging. A green light indicates that the battery is fully charged.
You can find the MacBook Pro User Guide here (this is not for the latest MacBook Pro, but the information about the MagSafe adapter is true for the newest model):

It sounds like you are not getting the amber light indicating your computer is charging, and you are noticing that the battery level is depleting. I recommend resetting your System Management Controller when something like this is occurring:
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
- Shut down the computer.
- Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
- On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
- Release all the keys and the power button at the same time.
- Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
